IMPROVEMENT IN RAILROAD SWITCHES.

Specification forming part of Letters Patent No. l 36,895, dated March 18, 1873.

" a detail horizontal section of the movable frgrail, showing the invention. Fig. 4 is a detail side view oif one of the straps by which the same is fastened.

Similar letters ot' reference indicate correspondin g parts.

The invention consists in the improvement of railroad switches, as hereinafter fully described and` subsequently pointed out in the claim.

lhe letter A in the drawing represents the line of the main track, and B is a branch track O O are the switch'rails, connected by a rod, D, with a crank, a, or equivalent device, to the switch-lever E, so that by moving said lever the switch-rail O may either be brought in line with the main track A, as by full lines in Fig. l, or with the branch track B, as by dotted lines in the same figure. At the -point where the rails of the two tracks A B cross each other, and where usually atriangular frog is placed, is arranged a movabl'ctshort rail, F, which is, by straps b b, connected vith the crossing-rails, as shown in Fig. 3, and which is further connected, bypa rod, d, with another crank, e, ofthe lever E.

The straps b b are so made or constructed with Velon gated bolt-l1oles, as shown in Fig. 4, as to al# low the frog-rail F to be swun ginto line with the railA, or with the rail B, as may be desired. Being connected with the lever E, the frog-rail F Will be moved simultaneously with the switchrails C, but in opposite direction thereto, in such manner that when the switch is brought in line with the main track A the frog-rail also will be brought into line with that rail of the track A in which it is placed, as is clearly shown by the full lines in Fig. l; and when the switch is brought in line with the track B the frog-rail F will be brought in line with that rail of the track B in which it is placed, as indicated by dotted lines in Fig. l. In either case the wheels of the train passing over the connected track will find continuous rails, and no obstructions similar to those usually offered by railroad frogs.y

I am aware that the movable short rail is not new in itself, and I do not wish to be un'- derstood as making any claim thereto.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The straps b b connecting the swinging frograil F to the crossing-rails A B, and made with elongated bolt-holes to allow the requisite vibration of the rail F, as set forth.

DON JUAN ARNOLD.
